Installation

LENS MOUNTING

The camera can use a ﬁxed iris, manual iris or auto iris lens. The camera is factory set for a CS-mount

lens, but is easily adjusted for a C-mount lens.

C-Mount Lens Only -

Rotate the back focus adjustment fully counterclockwise before

installing the C-mount lens (refer to the section on

Back Focus Adjustment

2. Remove the cosmetic trim ring from the back of the camera (refer to Figure 1). Set the lens

mode selector switch on the side of the camera to AIV (auto iris video drive lens) or AID (auto

iris DC drive lens). Refer to the

Switch Settings

section. Switch setting is determined by the

type of lens used.

3. Screw the lens onto the lens mount. Be careful to prevent dust from entering the space

between the lens and the CCD element. If necessary, use clean, compressed air to remove any

foreign matter.

4. Thread the lens cable through the cosmetic trim ring.

5. Connect the auto iris lens to the four-pin connector located on the side of the camera.

Pin connections for the iris drive connector are as follows:

bottom camera mounting. The mount adapter may be ﬁtted to the top or bottom of the camera.

The camera is shipped with the mount adapter located on the top of the camera.

To change the mount adapter position:



Remove the four screws from the mount adapter

located on the top of the camera.



Remove the trim cover from the bottom of the

camera by prying it loose. Place the trim cover on

the top of the camera where the mount adapter

was removed. Press into place.



POWER AND VIDEO CONNECTIONS

The MC3651H-2 camera is designed to operate from a 12 VDC or 24 VAC power supply. The power

supply connections are shown in Figure 1. The LED on the back panel of the camera indicates that

power is connected. Use only a Class 2 isolated power supply. Power consumption is less than ﬁve

watts.

Figure 4.

Power Supply Connections

To connect the camera power and video:

1. Remove the cosmetic trim ring from the camera (refer to Figure 1). Thread cabling through the

rear cover.

2. Connect the power cable to the two-pin power connector on the back of the camera using the

terminal block connector (provided). Refer to Table A for the recommend wire gauge and

wiring distances.

3. Connect a video cable to the SIGNAL OUT connector (BNC) on the back of the camera. Refer to

Table B for the type of video coaxial cable to use.

AC operation only -

If you are wiring more than one camera to the same transformer, connect one

side of the transformer to the same terminal on all cameras, and connect the other side of the

transformer to the remaining terminal on all cameras. Failure to connect all of the cameras the same

way will cause the cameras to be out of phase with each other and may produce a vertical roll when

switching between cameras.

Table A.

Recommended Wire Gauge and Wiring Distances

The following are the recommended maximum distances for 24 VAC applications and are calculated

with a 10-percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for

AC-powered devices.)

Wire Gauge

Example:

A camera that requires 10 vA and is installed 283 feet (86 m) from the transformer would

require a minimum wire gauge of 20 AWG.

NOTE:

Wire gauges are standard AWG or metric sizes. Distances are calculated in feet; values in

parentheses are meters.

Lens Setup and Focus Procedures

Video Drive Auto Iris Lens

When a video drive auto iris lens is used, the lens mode selector switch must be set to AIV. Switch

the ESC and AGC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video

output level of 1V peak-to-peak). Switch the AGC ON. To focus, fully open the iris by covering the lens

with a suitable neutral density (ND*) ﬁlter. Set the lens focus to inﬁnity (far). Select the scene to be

viewed. Use the back focus adjustment ring (refer to the

Back Focus Adjustment

section) to focus on

the selected scene. Remove the ND ﬁlter and set the lens focus as required.

Direct Drive (DC) Auto Iris Lens

Set the lens mode selector switch to AID. Switch the ESC ON. Use an appropriate screwdriver to turn

the lens level potentiometer (refer to Figure 1) fully clockwise. Next, slowly adjust the potentiometer

counterclockwise until the optimum picture is obtained (video output level of 1V peak-to-peak).

To focus, fully open the iris by covering the lens with a suitable neutral density (ND*) ﬁlter. Select the

scene to be viewed. If the viewed scene is 6.5 feet (2 m) away or farther, set the lens focus to inﬁnity

(far). Use the back focus adjustment ring (refer to the

Back Focus Adjustment

section) and focus on

the selected scene. Remove the ND ﬁlter and set the lens focus as required.

Fixed Lens

To focus, set the lens focus to inﬁnity and view an image greater than 6.5 feet (2 m) away. Focus the

image with the back focus adjustment ring (refer to the

Back Focus Adjustment

section). Set the lens

focus as required.

Manual Iris Lens

To focus, open the iris fully and set the lens focus to inﬁnity. View an image greater than 6.5 feet

(2 m) away. Focus the image with the back focus adjustment ring (refer to the

Back Focus Adjustment

section). Adjust the lens focus, set the iris for the best picture quality. The largest aperture gives the

best light sensitivity, the smallest aperture the greatest depth of ﬁeld.

Zoom Lens

Set the lens focus to inﬁnity (far) and fully open the iris by covering the lens with a suitable neutral

density (ND*) ﬁlter. Zoom out to the widest ﬁeld of vision and view a distant object. Adjust the back

focus adjustment ring until the object is in focus (refer to the

Back Focus Adjustment

section).

Next, zoom fully in and adjust the lens focus until the object is again focused. Repeat these steps until

the full zoom range may be viewed with the minimum loss of focus.

* NOTE:

For best results in outdoor lighting situations use an ND3 ﬁlter to focus the camera.

Back Focus Adjustment

The back focus adjustment is located at the front of the camera and is accessible from either side of

the case.

To adjust the back focus:

1. Loosen the two back focus locking

screws (one on each side).

2. Turn the back focus ring until the object

is in focus.

3. When the back focus adjustment is

satisfactory, tighten the locking screws.

Do not over tighten the locking screw or

force the back focus adjustment ring.

Digital Slow Shutter

Digital slow shutter slows the picture frame rate and increases the camera sensitivity under

low light conditions. Depending on the number of ﬁelds of integration, the picture will develop

a granular appearance and motion may show some lag, resulting in a stereoscopic effect or

streaking on fast-moving objects. These effects increase as the number of ﬁelds of integration

increases.

For the DSS mode to operate correctly set the OPT switch to OFF. The camera has four DSS

Camera Synchronization (AC Operation Only)

When using more than one camera power supply, a brief vertical roll may occur on the monitor when

a camera view is switched. To eliminate vertical roll, adjust the phase control by synchronizing, or

line-locking, the cameras to one another. Use the phase potentiometer located on the side of the

camera (refer to Figure 1) to make adjustments.

It may be necessary to have two people in communication when synchronizing the cameras: one

person at the camera and another person at the monitor to observe the vertical roll and the effect of

any adjustments made at the camera.

To synchronize the cameras do the following:

1. Choose a reference camera to which all other cameras will be phased.

2. Select a camera and synchronize it to the reference camera by turning the phase adjustment

control clockwise and/or counterclockwise.

3. Each time an adjustment is made, switch back and forth between the camera you are

adjusting and the reference camera. Repeat this process as many times as necessary, until the

roll between the cameras is no longer noticeable.

4. Adjust the phase of all other cameras by repeating steps 2 through 3. Always adjust to the

reference camera selected in step 1.

NOTE:

The preferred method for camera phase adjustment is to use a dual trace oscilloscope to align

the vertical sync pulses of the reference camera to the selected camera(s).
